2-2. Combination conditions for indoor unit and
outdoor unit
2-2-1. The capacity code for indoor unit, the capacity code is decided for each capacity rank.
2-2-2. The capacity codes of outdoor units are decided at each capacity type. The maximum number of connectable
indoor units and the total value of capacity codes of the indoor units are also decided.
NOTE
Compared with the capacity code of the outdoor unit, the total value of capacity codes of the connectable indoor
units differs based on the height difference between the indoor units.
When the height difference between the indoor units is 49 ft (15 m) or less
If “Medium Static Ducted Type (MMD-AP***BH)” is excluded in the system: Total indoor capacity code must be
between 80% and 125% of the capacity of the outdoor unit.
Total indoor capacity code must be between 80% and 120% of the capacity of the outdoor unit.
If “one of 007, 009 or 012 of 4-way Air Discharge Cassette type (MMU-AP***H*)” is included in the system:
Total indoor capacity code must be 80% - 105%.
When the height difference between the indoor units is over 49 ft (15 m)
Total indoor unit capacity code (Equivalent to Capacity) must be between 80% and 105% of the capacity of the
outdoor unit.
If “one of 007, 009 or 012 of 4-way Air Discharge Cassette type (MMU-AP***H*)” is included in the system:
Total indoor capacity code must be 80% - 105%.
